Title: Charge et son procede de production
Inventor: AHO OUTI
IPC: D21H17/69
Filed: 2002-04-24
Granted: 2011-03-22
Abstract: La présente invention concerne une charge comprenant des fibrilles de cellulose ou de lignocellulose sur lesquelles des particules de matière diffusant la lumière ont été déposées, ainsi qu'un procédé pour produire ladite charge. Dans la charge selon cette invention, un dérivé alkylé de cellulose, tel que de la carboxyméthylcellulose (CMC), a été sorbé sur les fibrilles. Le procédé pour préparer une telle charge à partir d'une matière source contenant des fibrilles de cellulose ou de lignocellulose consiste d'abord à produire une suspension de fibrilles, dans laquelle se trouvent des matières sources d'alimentation produisant un sel inorganique ou organique qui, lorsqu'il se précipite, donne un pigment diffusant la lumière. La charge selon cette invention présente de très bonnes propriétés de résistance et son utilisation permet notamment d'obtenir une bonne résistance d'adhésion. On peut augmenter la concentration en pigment minéral dans le papier et réduire le grammage du papier, sans détériorer les autres propriétés fondamentales du papier.
